A heat exchanger for a refrigerated merchandiser includes a fan housing having an asymmetrical configuration. The fan housing can include a first section with a first open outlet and a second section with a second open outlet. A first fan is positioned in the first section and configured to create a first airflow through the first open outlet. A second fan is positioned in the second section and configured to create a second airflow through the second open outlet. An evaporator is in fluid communication with the first open outlet and second open outlet. The first section is asymmetrical about a first section central axis and the second section is asymmetrical about a second section central axis.

An evaporating device includes: an evaporator, a defrost heater, and an evaporation pan, wherein the evaporation pan is made of aluminum and the inner side of the evaporation pan is coated with a surface treatment to improve the melting of ice in the evaporation pan.

A refrigerator includes a cabinet including a refrigerating compartment and an evaporation chamber, a first door, a housing in the first door, an ice making room defining a cool air inflow hole and a cool air discharge hole, a chiller room defining a cool air discharge hole, a second door connected to the first door, a partition wall defining the ice making room, the chiller room, and a communication hole, a damper opening and closing the communication hole, a cool air supply duct connecting an outlet of the evaporation chamber and the cool air inflow hole to supply cool air of the evaporation chamber to the ice making room, and a cool air return duct having a first inlet connected to the cool air discharge hole of the ice making chamber and a second inlet connected to the cool air discharge hole of the chiller room.

Beverage coolers for storing and cooling bottled beverages. A beverage cooler may include a cooling chamber cooled by a refrigeration system, and openings in the cooling chamber for receiving bottled beverages to be chilled. The openings may have doors and/or seals to minimize heat exchange between the cooling chamber and the environment with or without bottles disposed in the openings. Each of the openings may have a visual indicator, such as a plurality of LEDs, configured to indicate the temperature of the bottle disposed in the opening.

A refrigerator includes: a storage compartment; an evaporator configured to generate cold air through heat exchange; a duct comprising a channel formed therein and through which the generated cold air flows and a cold air outlet through which the cold air is discharged to the storage compartment; a fan configured to supply the generated cold air to the storage compartment through the channel; and a cold-air control unit provided in the channel and to control a discharging amount of cold air discharged through the cold air outlet. The cold-air control unit includes a damper movable according to strength of the generated cold air supplied by the fan to adjust the cold air outlet.

Methods and systems are provided for an air conditioning system. An example method of determining current through a compressor suction valve in a vehicle air conditioning (AC) system is provided, the AC system comprises an evaporator fan and the method includes determining the speed of the evaporator fan and determining the current through the suction valve based on the speed of the evaporator fan.

A scroll casing has a scroll portion, a discharge portion provided with a discharge port, and a tongue portion. An extended plate has, in a cross section obtained by cutting in a thickness direction, a change point, at which an enlargement ratio of an area of the cross section is enlarged so as to be larger on a downstream side than that on an upstream side due to a change of inclination. In the extended plate, an angle θ1, and an angle θ2 satisfy a relationship of either 0≤θ2<θ1 or 0<θ2≤θ1. A distance L1 and a distance L2 satisfy a relationship of L2<L1.

A method for controlling an operation of a refrigeration appliance includes controlling a first cooling routine for a first compartment via a flow of a thermal exchange media to a first evaporator. The method further includes controlling a heating routine in response to a setpoint temperature being greater than the temperature of the first compartment. The heating routine includes activating a heating element and a fan in the first compartment over a first interval and deactivating the heating element and the fan over a second interval. The heating routine continues by activating the first interval and the second interval over alternating time periods. In response to the temperature of the first compartment being greater than or equal to a target temperature associated with the setpoint, the method may control the operation of the appliance by returning to the cooling routine.

A refrigerator appliance includes a cabinet that defines first and second compartments. A fan assembly is configured to direct cooled air from a cooling assembly into the first and second compartments. The fan assembly includes a housing that defines an inlet, a first outlet, and a second outlet. The first outlet is in communication with the first compartment, and the second outlet is in communication with the second compartment. A fan is positioned within the housing and is configured to direct the cooled air from the inlet toward the first and second outlets. A damper assembly is configured to selectively obstruct one of the first outlet and the second outlet.

A refrigerator includes a cabinet formed with a chamber, a partition wall configured to partition the chamber into a storage space and an air flow path and including a discharge port and a suction port, and a heat exchanger provided in the air flow path, in which the air flow path includes a discharge flow path to guide air discharged to the discharge port, the discharge flow path has an inlet closer to a first side edge of the partition wall, and the suction port is formed closer to a vertical centerline of the partition wall than either of a first or second side edge of the partition wall.
